In Bhagalpur, India, understanding the UV Index is crucial for safeguarding your skin and overall health. As the sun casts its warm glow over this Cwa climate zone, the UV levels can fluctuate significantly throughout the day, peaking between 10:00 AM and 12:00 PM at a striking 10—a level where unprotected skin risks quick burns and long-term damage. Awareness of these UV levels not only helps in preventing sunburn but also plays a vital role in reducing the risk of skin cancer and premature aging. With typical exposure risks soaring during the day, it’s essential for residents and visitors alike to stay informed and take necessary precautions to enjoy the sun safely.
The UV Index follows a dynamic pattern throughout the day, peaking sharply during the mid-morning to early afternoon. Starting from a mild 3 at 7:00 AM, the index climbs steadily to reach a staggering 10 between 10:00 and 11:00 AM—the highest point of the day, signaling a significant risk of harm from unprotected sun exposure. As the sun moves overhead, it dips slightly to 9 at noon before beginning a gradual descent. By 2:00 PM, it drops to 5, and by late afternoon, it wanes further, reaching a low of 1 by 5:00 PM. As the sun sets, the UV index nearly vanishes entirely, falling to 0 by 6:00 PM. This data highlights the importance of sun protection for those venturing outdoors, especially during the peak hours of 10:00 AM to 2:00 PM.
